hASC Expansion

in Spinner Flasks

1. A sufficient quantity of hASC prepared during the inoculum

production (see Subheading 3.1).

2. The corresponding chemically defined, xeno-free cultivation

medium prepared according to the manufacturer’s instructions

and stored at 4 C in the dark until use (see Note 6).

3. 125 mL spinner flasks (Corning®).

4. A CO2 incubator containing a magnetic stirrer platform (see

Note 7).

5. ProNectin® F MCs (see Note 10).

6. The enzymatic dissociation reagent and buffer of choice (see

Note 9).

hASC Expansion

in the BioBLU®

1. A sufficient quantity of hASC cells prepared during the inocu-

lum production (see Subheading 3.1).

2. The corresponding chemically defined, xeno-free cultivation

medium prepared according to the manufacturer’s instructions

and stored at 4 C in the dark until use (see Note 6).

3. BioBLU® 0.3c bioreactor vessels, the corresponding DAS-

GIP® Parallel Bioreactor System (Eppendorf), and conven-

tional compatible pH probes.

4. ProNectin® F MCs (see Note 10).

5. The enzymatic dissociation reagent and buffer of choice (see

Note 9).

2.4

Process

Analytics

1. Sample drawn from the cultivation systems (see Subheadings

3.2 and 3.3).

2. The enzymatic dissociation reagent and buffer of choice (see

Note 9).

3. A CO2 incubator with integrated orbital shaker (see Note 7).

Methods

The following protocols, developed for the expansion of the hASC

line hASC52Telo, include the preliminary preparation of the media

and MCs, inoculum production, preparation of the cultivation sys-

tems, inoculation, sampling, analytics, and cell harvest. With minor

modifications, these protocols may be adapted for the expansion of

other patient adipose tissue-derived mesenchymal stem cells.

3.1

T75-Flask-Based

Inoculum Production

1. Prepare 20 mL of cell culture medium (see Note 6) for the

inoculum production in a T75-Flask by pre-warming it to

37 C.

2. Coat the T75-Flasks with 15 mL of SynthemaxII-SC work-

ing solution (see Note 8).
